Configuration based client for OAuth authorization with arbitrary services and applications

Techniques for generic authentication with arbitrary services are provided. A request to authorize with a first service, of a plurality of services, using the OAuth protocol, is received by a generic client library, from a first application. A set of parameters specific to an implementation of the OAuth protocol provided by the first service are identified in a configuration file. An HTTP request is generated based on the set of parameters identified in the data structure, and the first application is authorized with the first service via the OAuth protocol using the generated HTTP request.
